ARK Performance to unveil Legato Concept at 2013 SEMA

Article by Anita Panait, on October 9, 2013

ARK Performance will showcase another performance luxury coupe concept at the 2013 SEMA Show in Las Vegas scheduled on November 5-8. The Legato Concept is still powered by the production-based Hyundai 3.8-liter Lambda V6 engine that powers the Genesis Coupe on which it is derived. However, the engine is improved to 4.0-liters for 400 hp of output and 425 lb.-ft. of torque. The engine block features a Brian Crower (BC) 4.0 Stroker Kit with JE Pistons and BC 4340 crankshaft, connecting rods, and ARK oil cooler – all ensuring optimized output with superior durability.

Thanks to an ARK intake system and headers, engine breathing at high rpm has been improved, while a lightweight pulley kit cuts down unnecessary power losses from ancillary equipment. The concept also features an ARK dual-mass flywheel and carbon clutch kit that ensure efficient power transfer from the engine to the road.

Rideability is ensured by an ARK DT-P coil-over suspension system, lightweight Rays Engineering G25 wheels and Nitto NT05 tires, complemented by an ARK carbon brake pads for better stopping power. The interior of this luxury performance concept features Takata Drift Pro LE seats, AiM Sports Strada GT steering wheel, and digital gauge cluster as well as a Rockford Fosgate premium sound system.

Helping emphasize the emphasize the exterior profile of the new Genesis Coupe as well as its broad shoulders and wide stance are the car’s arching roofline and tapering greenhouse. This aggressive appearance of the Genesis Coupe is further highlighted by the maximized depth between the fenders and the greenhouse.

Also underscoring the aggressiveness of the Genesis Coupe, while allowing the engine to breathe better, are the larger openings in the front fascia. This is beautifully matched on the rear by dual asymmetrical exhaust tips integrated with the blackout rear diffuser treatment.

Both engines of the new Hyundai Genesis Coupe have been upgraded dramatically, allowing the South Korean sports car to boast of not just a new design but also an increase in performance. For instance, the Genesis Coupe’s 3.8-liter Lambda DOHC V6 engine now employs direct-injection technology, allowing this dynamic mill to offer 14 percent more max output (plus 42 hp to 348 hp at 6,400 rpm) and 11 percent more peak torque (plus 29 lb.-ft. to 295 lb.-ft. available at 5,300 rpm on premium fuel).

Interestingly, this V6 engine is versatile enough to use regular fuel, thanks to the lambda-engine anti-knock technology. With its capability, the 3.8-liter Lambda DOHC V6 engine allows the Genesis Coupe to sprint from zero to 60 mph in the lower five-second range and achieve an electronically limited top speed of 149 mph. Moreover, the Lambda V6 intake system now makes use of an intake sound induction pipe into the cabin.
